Homebrew PCBs

While at the local Wal-mart I picked up a Scotch (3M) TL901 9"
laminator for $US25.00. After taking it apart and verifying its
usability for toner transfer, I decided to make it part of a
documented project.

So far, I've taken a bunch of pictures of the laminator's insides, and
I've ordered a PID temperature controller from
http://www.auberins.com for $US35.00.

In the coming weeks I'll try to throw together a brief discussion of
what I did to make it a toner-transfer device.

P.S. I was surprised to find that the 3M laminator had genuine
electronics controlling the temperature (100 and 105 degC setpoints
only), instead of a bi-metal thermostat. However, I decided to replace
the controller rather than hack it, mostly because it wasn't isolated
from the mains voltage.
